Skyscrapers are exceptionally tall
buildings that often dominate the
skylines of large cities. They are
generally filled with offices and
apartments, built to provide as
much work and living space as
possible in areas where horizontal
space is scarce and extremely
expensive.

There is no standard height requirement for a
building to be labeled a skyscraper. However,
“skyscrapers” in modern times are generally
considered to be taller than “high-rises.” For
example, a building with twenty-five stories would
most likely be considered a high-rise, while a
building with thirty-five stories might be considered
a skyscraper.

As such, it could be said that the term
“skyscraper” is relative to height of the skyline in
which the building exists. Buildings reaching
heights beyond 300 meters, however, are always
called skyscrapers. In fact, they are classified as
“supertall” skyscrapers. Similarly, skyscrapers
higher than 600 meters are referred to as
“megatall.”

The term “skyscraper” originated in the United States
during the late 1800s. At the time, architects began
utilizing steel frames, allowing for the construction of
buildings beyond 10 stories in height. These
“skyscrapers” dominated the skylines of major
American cities, such as New York, Detroit and
Chicago.

The Home Insurance Building in Chicago was
one of the first of these steel-frame
“skyscrapers.” Constructed in 1885, the
building was just 10 stories high - 42 meters
tall!

Less than 50 years later, the Empire State
Building was built in Manhattan, New York
City in 1931, becoming the first building in
the world to have more than 100 stories.
At 381 meters tall, the Empire State
Building remained the tallest building in
the world for more than 40 years until it
was surpassed by the World Trade Center
in 1972. Also located in Manhattan, the
World Trade Center was 417 meters tall.

Comparatively, the tallest building in the world
today is the Burj Khalifa, a “megatall”
skyscraper in Dubai. Completed in 2010, the
Burj Khalifa is 828 meters tall - nearly twice as
tall as the World Trade Center and twenty
times as tall as the Home Insurance Building in
Chicago!
